/* fonts.css — self-hosted signature typefaces for Star OS.
 *
 * The design languages already NAME these faces:
 *   packages/theme/src/design/languages/star-os.ts
 *     --star-font-ui  : "Oxanium", …      (retrofuturist UI voice)
 *     --star-font-mono: "IBM Plex Mono", … (data / receipts)
 *   packages/web-shell/src/theme-win98.css
 *     "Pixelated MS Sans Serif"           (retro win98 chrome)
 *
 * …but nothing ever LOADED them, so every theme fell back to system-ui and the
 * VOICE identity was unshipped. This file makes the named faces resolve.
 *
 * Self-hosted only (no third-party CDN hotlink) → offline-deterministic and
 * consistent with the no-tracking promise. woff2 binaries live under
 * public/fonts/ and are copied into dist/fonts/ by build.ts; this stylesheet is
 * copied to dist/fonts.css and linked in the head BEFORE theme-win98.css.
 *
 * font-display: swap → text paints immediately in the fallback metric, then
 * swaps to the signature face once the woff2 arrives (no invisible-text FOIT).
 *
 * Provenance:
 *   Oxanium        — OFL 1.1 (Google Fonts), variable file pinned per weight.
 *   IBM Plex Mono  — OFL 1.1 (Google Fonts).
 *   Pixelated MS Sans Serif — the 98.css retro face (MIT-distributed).
